Pranatoshini

The Pranatoshani Tantra states that:

1. The merit gained by worshipping Vishnu in a Shalagrama shila once is equivalent to that of conducting a thousand Rajasuya yajnas and donating the entire earth.
2. A person who is unable to undertake pilgrimage, donate articles to the needy and brahmins or conduct yajnas can gain mukti (liberation) by worshipping Vishnu in a Shalagrama shila.
3. Land situated within the radius of three yojanas of a Shalagrama shila becomes sacred to Vishnu even if that land is inhabited by mlecchas (non-Aryans). A devout worshipper who dies in such an area is never reborn again.
4. All sorts of auspicious activities (like taking ablution, donating articles to the needy and brahmins, undergoing austerities and conducting homa) grants merit for all eternity on being conducted in the vicinity of a Shalagrama shila.
5. All sorts of sins whether perceived in mind or committed in deeds for an entire year are destroyed by donating a Shalagrama shila to a brahmin.
6. The person who worships together 12 Shalagrama shilas for a single day earns the merit equivalent of worshipping 12 crore Shivalingas with lotuses made out of gold and residing in Varanasi for eight days.
7. The person who worships together 100 Shalagrama shilas attains Maharloka after death and is reborn as an emperor.
8. Moksha is undoubtedly obtained by the person who worships a Shalagrama shila and Dvaravati shila together.
